Take a vacuum line from the lower front of your carb and hook it to your distributer vacuum advance. Take another from the front of your carb and run it to your EGR valve. It should be beside the carb on the intake manifold.The underhood end should mount to a factory installed nipple on the rear of the intake manifold with another piece of rubber vacuum hose. If there is no nipple then plug it into the rear of the carb. If the steel line is missing, then get a piece of brake line and use it. The distance is too far for a piece of rubber hose.Here is a diagram, there is also usually one underneath the hood on a white label. Let me know if you have questions, thanks. Dan. Category: Chevy.
